Comprehensive Geriatric Assessment
A multidimensional, interdisciplinary diagnostic process used to evaluate the medical, functional, psychological, and social needs of older adults, forming the foundation of geriatric rehabilitation planning.
Full Definition
Comprehensive Geriatric Assessment (CGA) is a structured, evidence-based diagnostic and planning process that evaluates multiple dimensions of an older person's health status, including medical comorbidities, functional ability, cognitive and mental health, nutritional status, medication review, falls risk, and social and environmental circumstances. CGA is distinguished from standard medical assessment by its holistic, team-based approach and its explicit linkage to an individualised care plan. Multiple systematic reviews have demonstrated that CGA improves patient outcomes, reduces hospital readmissions, and increases the likelihood of living at home after hospitalisation. Editors should always capitalise 'Comprehensive Geriatric Assessment' as a proper noun and introduce the abbreviation CGA on first use. The term should not be shortened informally to 'geriatric assessment' without qualification in formal documents.
Usage
Usage note: Capitalise as 'Comprehensive Geriatric Assessment'. Abbreviate as CGA after first use. Distinguish from a general geriatric review by emphasising the structured, multidimensional, team-based nature.
